I have found that the link to Veijo Vilva's Lojban Web Archive
http://www.animal.helsinki.fi/lojban/
leads now to the http://www.lojban.org
Is the site shut down forever?
I will particularly miss the gismu dictionary search engine.
I think it was the only tool available on-line which allowed to
search for English keywords.
